Example 6 with EventBus

use of io.vertx.core.eventbus.EventBus in project vert.x by eclipse.

@Test
public void testReplyFromWorker() throws Exception {
    String expectedBody = TestUtils.randomAlphaString(20);
    startNodes(2);
    CountDownLatch latch = new CountDownLatch(1);
    vertices[0].deployVerticle(new AbstractVerticle() {

        @Override
        public void start() throws Exception {
            vertices[1].eventBus().<String>consumer(ADDRESS1, msg -> {
                msg.reply(expectedBody);
            }).completionHandler(ar -> {
                assertTrue(ar.succeeded());
                latch.countDown();
            });
        }
    }, new DeploymentOptions().setWorker(true));
    awaitLatch(latch);
    vertices[0].eventBus().send(ADDRESS1, "whatever", reply -> {
        assertTrue(reply.succeeded());
        assertEquals(expectedBody, reply.result().body());
        testComplete();
    });
    await();
}

        msg.reply(new JsonObject().put("value", "Hello " + msg.body().getString("value")));
    });
    eb.consumer("echo", (Message<JsonObject> msg) -> msg.reply(msg.body()));
    eb.consumer("echo2", (Message<JsonObject> msg) -> {
        if ("send".equals(msg.body().getString("response_type"))) {
            eb.send("echo2_response", msg.body());
        } else {
            eb.publish("echo2_response", msg.body());
        }
    });
    TcpEventBusBridge bridge = TcpEventBusBridge.create(vertx, new BridgeOptions().addInboundPermitted(new PermittedOptions().setAddress("hello")).addInboundPermitted(new PermittedOptions().setAddress("echo")).addOutboundPermitted(new PermittedOptions().setAddress("echo")).addInboundPermitted(new PermittedOptions().setAddress("echo2")).addOutboundPermitted(new PermittedOptions().setAddress("echo2_response")));
